Before you install the residential solar power system, you have to check with the local authorities in case you require prior approval. At times system has to be instated by licensed contractors.
If you want to decide upon the best residential solar power system, then it can be a challenging task, since there are numerous competitive products in the market. Thus it becomes essential to gather the information on how these systems work and what are the constituents required, to make these.
These systems are very expensive if you have to buy them commercially. Making them yourself is a good idea. In a few years the residential solar systems make their costs back.
Before you begin on the task of making the system it would be better if you asses the kind of power consumption that your house requires. It will provide you with the rough indication of the size and the cost of system required. For this you can take an average of a few days of electricity consumption.
A standard residential solar power system consists of photovoltaic panels, batteries, controller and an inverter. Several panels are wired together to meet the energy requirements of the house.
By wiring several panels together, the output power increases and low output voltage is maintained at the same time.
The whole set can be mounted anywhere, but it is best to mount it on the roof so that it receives maximum sunlight. If the roof is flat, you will require some inclined support since the photovoltaic arrays need to face the sun.
The panels of the solar power systems are usually heavy. This accounts for consideration during the mounting procedure. However, there are smaller panels also available that are called solar shingles and they are supposed to set up over the entire roof. These panels are wired to the controller that is connected to batteries. A controller monitors the voltage levels of the batteries and panels.
They disconnect the panels when the voltage exceeds. This prevents the panels to be overcharged.
